Fairy Chess Pieces
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some unorthodox chess problems, known as fairy chess. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces can have the same name in various contexts. Most are symbolised as inverted or rotated icons of the standard pieces in diagrams, and the meanings of these "wildcards" must be defined in each context separately. Pieces invented for use in chess variants rather than problems sometimes instead have special icons designed for them, but with some exceptions (the princess, empress, and occasionally amazon), many of these are not used beyond the individual ga ...

Chess Piece
A chess piece, or chessman, is a game piece that is placed on a chessboard to play the game of chess. It can be either White and Black in chess, white or black, and it can be one of six types: King (chess), king, Queen (chess), queen, Rook (chess), rook, Bishop (chess), bishop, Knight (chess), knight, or Pawn (chess), pawn. Chess sets generally come with sixteen pieces of each color. Additional pieces, usually an extra queen per color, may be provided for use in Promotion (chess), promotion or handicap games. Number Each player begins with sixteen pieces (but see the #Definitions, subsection below for other usage of the term ''piece''). The pieces that belong to each player are distinguished by color: the lighter colored pieces are referred to as "white" and the player that controls them as "White", whereas the darker colored pieces are referred to as "black" and the player that controls them as "Black". In a standard game, each of the two players begins with the following si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferz
The ferz or fers is a fairy chess piece that may move one square diagonally. It was used in orthodox chess and in Shatranj form of chess before being replaced by the queen. History and nomenclature The ferz is a very old piece, appearing in chaturanga and shatranj, the ancestors of all chess variants; it also featured in games such as Tamerlane chess. The ferz was a standard chess piece until the modern moves of queen and bishop were developed around the 15th century, with the ferz being replaced by the former. The ferz also appears in some large historical shogi variants, such as in dai shogi under the name ''cat sword'' (). The Thai variant of chess, makruk, retains the ferz from shatranj as the "Met", both as a starting piece and as the only pawn promotion option. Thus, much of shatranj endgame theory is also valid for makruk. The piece was originally called the (Sanskrit for "minister" or "counsellor"), which was translated by the Persians to ''farzin'' or ''farzīn'' ...

Shogi Variant
A shogi variant is a game related to or derived from shogi (Japanese chess). Many shogi variants have been developed over the centuries, ranging from some of the largest chess-type games ever played to some of the smallest. A few of these variants are still regularly played, though none are as popular as shogi itself. The drop rule, often considered the most notable feature of shogi, is absent from most shogi variants, which therefore play more like other forms of chess, with the board becoming less crowded as pieces are exchanged. This is especially true for variants larger than shogi itself. In fact, the largest well-known variant that features the drop rule is the 11×11 game wa shogi. Predecessors of modern shogi Some form of chess had almost certainly reached Japan by the 9th century, if not earlier, but the earliest surviving Japanese description of the rules of chess dates from the early 12th century, during the Heian Period, Heian period.

Hippogonal
A hippogonal (pronounced ) chess move is one similar to a knight's move. That is, a leap ''m'' squares in one of the orthogonal In mathematics, orthogonality (mathematics), orthogonality is the generalization of the geometric notion of ''perpendicularity''. Although many authors use the two terms ''perpendicular'' and ''orthogonal'' interchangeably, the term ''perpendic ... directions, and ''n'' squares in the other, for integer values of ''m'' and ''n''. It need not be a 2:1 ratio for m and n. A specific type of hippogonal move can be written ''(m,n)'', usually with the smaller number first. For example, the knight itself moves two squares in one orthogonal direction and one in the other—it moves hippogonally. It is a (1,2) hippogonal mover, sometimes referred to as a (1,2) leaper. Other hippogonally moving pieces include the camel, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fork (chess)
In chess, a fork is a tactic in which a piece multiple enemy pieces simultaneously. The attacker usually aims to capture one of the forked pieces. The defender often cannot counter every threat.

Pin (chess)
In chess, a pin is a tactic in which a defending piece cannot move out of an attacking piece's line of attack without exposing a more valuable defending piece. Moving the attacking piece to effect the pin is called ''pinning''; the defending piece restricted by the pin is described as ''pinned''. Only a piece that can move any number of squares along a horizontal, vertical, or diagonal line (i.e. a bishop, rook, or queen) can pin. Any piece can be pinned except the king. The pin is one of the most powerful chess tactics. The inverse of a pin is a ''skewer'', in which a more valuable piece under direct attack may move to expose a less valuable piece to an attack. Types Absolute pin An ''absolute pin'' is one where the piece shielded by the pinned piece is the king. In this case it is illegal to move the pinned piece out of the line of attack, as that would place one's king in check (see diagram). A piece pinned in this way can still give check or defend another piece fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Check (chess)
In chess and similar games, check is a condition that occurs when a player's king is under threat of on the opponent's next turn. A king so threatened is said to be ''in check''. A player must get out of check if possible by moving the king to an unattacked square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot remove the check by any of these options, or if using any of these options would result in the player being in check by another piece, the game ends in checkmate and the player loses. Players cannot make any move that puts their own king in check. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or, in rare cases, two) of the player's pieces. Making a move that checks is sometimes called "giving check". Even if a piece is pinned against the player's own king, it may still give check. For example, in the diagrammed position ...

Janggi
Janggi (, also Romanization of Korean, romanized as ''changgi'' or ''jangki''), sometimes called Korean chess, is a Strategy game, strategy board game popular on the Korean Peninsula. The game was derived from xiangqi (Chinese chess), and is very similar to it, including the starting position of some of the pieces, and the 9×10 gameboard, but without the xiangqi "river" dividing the board horizontally in the middle. Janggi is played on a board nine lines wide by ten lines long. The game is sometimes fast paced due to the jumping cannons and the long-range elephants, but professional games most often last over 150 moves and so are typically slower than those of Chess, Western chess. In 2009, the first world janggi tournament was held in Harbin, Heilongjiang, China. Rules Board The board is composed of 90 intersections of 9 vertical files and 10 horizontal rows. The board has nearly the same layout as that used in xiangqi, except the janggi board has no "river" in the central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xiangqi
Xiangqi (; ), commonly known as Chinese chess or elephant chess, is a Strategy game, strategy board game for two players. It is the most popular board game in China. Xiangqi is in the same family of games as shogi, janggi, chess, Western chess, chaturanga, and Indian chess. Besides China and areas with significant ethnic Chinese communities, this game is also a popular pastime in Vietnam, where it is known as , literally 'General's chess', in contrast with Western chess or ', literally 'King's chess'. The game represents a battle between two armies, with the primary object being to checkmate the enemy's general (king). Distinctive features of xiangqi include the cannon (''pao''), which must jump to capture; a rule prohibiting the generals from facing each other directly; areas on the board called the ''river'' and ''palace'', which restrict the movement of some pieces but enhance that of others; and the placement of the pieces on the intersections of the board lines, rather th ...

Zebra (chess)
The zebra is a fairy chess piece that moves like a stretched knight. It jumps three squares horizontally and two squares vertically or three squares vertically and two squares horizontally, regardless of intervening pieces; thus, it is a (2,3)-leaper.Dickins (1971), p. 11 A lame zebra, which moves one step orthogonally and then two steps diagonally outwards and can be blocked by intervening pieces, appears as the elephant in janggi. Movement Value The zebra by itself is worth just below two pawns (appreciably less than a knight) due to its restricted freedom of movement on an 8×8 board. Its larger move is the main reason why it is weaker than a camel on an 8×8 board, even though the camel is colorbound and the zebra is not. A king, a bishop, and a zebra can force checkmate on a bare king; a king, a knight, and a zebra cannot; and a king, a camel, and a zebra cannot. The rook versus zebra endgame is a win for the rook. (All endgame statistics mentioned are for the 8×8 boa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
